Disposable shower strainer



FIG. 1 is a perspective view of a disposable shower strainer, showing my new design;

FIG. 2 is an enlarged top plan view thereof, the bottom plan view being a mirror image thereof; and,

FIG. 3 is a left-side elevational view thereof, the right-side elevational view, front elevational view, and rear elevational view all being identical thereto.

The broken lines showing a sink and drain in FIG. 1 depict environmental matter and form no part of the claimed design. 

I claim the ornamental design for a disposable shower strainer, as shown and described.
